Roof Control & Weather station

Roof control and weather station reading (including dust monitor and some of the indoor environmental sensors) is handled by a beckhoff PLC in the roof control cabinet.

Moxa-IO-modules

Many components are controlled or read out using Ethernet-connected Moxa I/O modules.

io1 & io3 & io5

These modules are located above the STELLA-1 rack, next to the calibration unit. Power comes from the fuse that also supplies PDU3.

1. io1,ip=161.72.132.122: Analog Input to read in SES dewar pressure (ch1) and SES vacuum pump pressure (ch2), CryoWifsip return (ch3), CryoWifsip supply (ch4)
2. io3,ip=161.72.132.124: temperatures: oil1, oilroom1, oil2, oilroom2, lounge, lab
3. io5,ip=161.72.132.99: Calibration unit: DO: halo1, halo2, thar1, thar2, rack1, rack2 ; DI thar1on, thar2on. Note that the relays in the racks are normally-closed, thus OFF means power is on, ON means power is off

internal ethernet network

the two telescopes and the ASIVA share a common private network. It is connected through a small ethernet switch in the rear part of the rack. The IPMI interfaces of the servers are also connected to this network.

uplink

The uplink is a SM fiber connected to the Residencia on the other side, while at STELLA it is connected to a media converter, which is connected to the firewall. .. We also run the BMK network from here, this is directly connected to the main switch through a single mode fiber. Both STELLA2_AG and WiFSIP are also connected directly via fiber to the SFP panel on the main switch.

SES calibration unit

Location

SES calibration unit

The SES calibration unit is situated on top of the STELA-1 telescope control rack. It is a black box about 1x1 m in size. To open it, about 8 screws need to be loosened on top of the unit.

Inside the calibration unit

SES calibration lamp locations

Inside the unit are 4 lamps. 2 ThAr-hollow cathode lams (the big glass tubes towards the front of the unit) and 2 Halogen lamps. Currently, 20W halogen lamps are in use.

Where are the spare lamps

SES spare lamps

The spare lamps are in a cupboard in the electronics room (where the calibration unit is also located). The Halogen lamps are 20W, 12V Osram lamps, several of those are located in a small cardboard box in that cupboard (see picture). Please do not touch the glass of the halogen lamp with your fingers when exchanging it, its best to wear gloves or use the wrapping of the lamp to hold it.

There are also spare ThAr lamps on site.
